My invention relates to dumping vehicles,l

one object being to provide a supporting structure for balancing or plvotally support.-

ing the buckets or receptacles preferably at intermediate points in their length to render their manipulation easy and certain in both opening and closing.

A. further object of my invent-ion is to provide an arrangement otA bucket and supporting frame in which the latter will form the bottoni wall of the bucket and. partially sustain the material', the bucket moving awaytherefrom in opening' to discharge the material. I

.\nother object is to provide a pair otI buckets, each pivotally supported preterably at. an intermediate point in its 'length and operated by connections to the adjacent or inner ends of the buckets which lowers or raises these adjacent ends to et'feet the open- ,ing and closing act ions.

e Another object is to provide a pair ot buckets willi sul'iporting trame work between them adapted to receive and support driving mechanism, and other objects of my invention will appeal' trom the following description.

The invention consists in the Vteaturcs and combination and arrangement ot' parts hereinafter described and particularly pointed out in the claims.

ln the accompanying drawings, Figure l is a side view of one forni ot' vehicle einbodying my invention; Fig. 2 is a sectional View taken longitudinally of the vehicle ot' Fig. l; Fig. 3 is a plan viewof the vehicle ot Fig. 1 with a portion broken away: Fi". iis a transverse sectional view through a vehicle of the form shown in Fig. 1 embodying my invention; Fig. 4 is a side view of a bucket detached; Fig. Lt" is a side view ot a side plate; Fig. 5 is a detail view of one way ot applying a motor to the vehicle` it being" understood. however, that the vehicle may be ot various toi-ins and driven or drawn in ditilteret'itways: Fig. (l is a. side view of two vehiclesI such as shown in Fig. 1 coupled together to make a composite vehicle, and

which may be used, at the headofa train of vehicles such as is shown in Fig. l, or may 'be used in other relations; Fig. 7 is a side, YBW of a train of vehicles of the form shown 1h Fig. 1 with a car or truck at the front for carrying a generating set and controller mechanism; Fig. 8 is a plan viewof Fig. 7; Fig. 9 indicates that certain features vot my invention may be embodied in another form of vehicle having two large carrying wheels and a truck wheel for steering, this vehicle carrying its own source of power, its own motor and controller; Fig. l0 indicates one way in which myinvention' may be embodied in a horse drawn vehicle. Figs. 11 and 12 arc views relating to one form of the carrying wheels. Figs. 13 and 14 are views relating to a wheel construction.

In 'the drawings, l indicates triangular shaped tirantes', one on each sido, made up of angle irons l converging upwardly and riv eted together at their upper ends and connected at. their ower ends by a horizontal' angle iron l.

strut 2, one on each side at points near their iii\'ei'giiig upper ends. i These trames support. the buckets as will be hereinafter described, and they are hung ir a main trame I- composed ot an angle iron extending horif/.ontally on each side of the iippafiitus, and having curved ends at 'front and' rear. For hanging the triangular supporting trames m this main trame. l provide springs ft and bolts 5, the said springs l'icaringon the under which are connected at their ends to the supplemental frames.

The triangular frame on one side of the he inclined' angle irons are` turther connected by a horizontal angle iron machine is connected with that on the other 10 extend which are riveted to the inclined angle irons and form the fixed bottom ot the Vreceptacles for holding the material of which the buckets form the movable parts. On the other lateral sides of the triangular frames I secure side plates 11, one at each side of the machine, each riveted to one of the .triangular frames and these side plates are of general triangular form and extend across the opening withinthetriangular supporting frame forming side 4closures therefor, land extend-ing beyond the inclined angle irons to form side guides for the movable buckets within which the buckets move.

The upwardly converging plates 10, to-

A a-d0or 11b whereby access may be had to the interior of the housing.

' i The buckets are composed of side plates 12,

andcurved, end plates 13, each being strengthened by angle iron bars 14, riveted along the top edges of the buckets and along thein curved end edges, and also across their lower edges as at 16. The buckets are hung on pivots 17 intermediate of their length, said pivots being carried upon links or swinging bars 18 pivoted at their lower ends to the corners of the triangular frames. The buckets are dumped by depressing their adjacent inner ends, for which purpose each has at its buckets.l and it carries a pin at 23 guided in a slot 24 inner end an ear or extension 19 overlapping the ear on the other bucket, and these ears are pivotally connected togetherat 20.A

At the meeting inner ends of the buckets on each side, a yoke piece 21 is pivoted extending on the outside of the side plates 11, and each connected at i'ts ends by a pin and slot at 22 with the upper inner ends of the The yoke plate is ot angle iron in a vertical hanger 25 lying outside of the side plates 11 and at a slight'distance there- 'from to admit a link 26 between it and the side plate, which link' 'is'connected to 'an arm 26 on a transverse shaft 27 bearing in side frame plates 11. operating lever 2S connected thereto.

the lower ends of the hangers, and in the This shaft has an The hanger 25'has at its upper end an inwardly projecting head which is'recessed to fit over the upper apex of the side plate. This construction is duplicated at the other side of the machine, though only one operating handle or lever 28 is used. f

In order to dump the buckets, the handle orlever 28 is lifted, and through the connections described the inner ends of the buckets are depressedfcausing them t0 turn on the pivots 17 of the supporting links or bars. 18 and throwin their lower ends away from the central sa die-like frame, and the inclined bottom plates'lO connected thereto', so that the material can slide down by l may be held in this position by a catc'h2S,

engaging the operating lever, and this" lever canbe released by forcing it down and latyerally slightly. As another means ot locking the buckets closed, I may use a pin 1.9 passing through one of the ends of the buckets'or their extensions and the yoke and side plate, and this pin may be left in. place when the vehicle is on a run of considerable distance. Vthen4 the buckets are closed, the weight of the material will' be sustained by the inclined bottom walls 10 andthe curved end walls 13, and with the buckets locked together and their meeting endsheld up, the

intermediate pivot bearings of the bucketswill be relieved from strain. Dumping can be effected by the application of little power to the hand lever28 after this is released, a-nd the locking pin, if used, is removed, bc-

cause in dumping, each'bucket is balancedv on the pivots intermediate ot its length, and

it requires but little force applied to the meeting ends of these buckets to depress them at this point and cause them to open.

lt will bev observed also that thebucket is hung to haveI approximately a rotary movement in respect to the pivots 17', andin closing by raising the 'inner end of the bucket a slight lifting movement is given to the lower end of the bucket instead of a direct movement toward the central frame, so that the discharge of the material'can be readily cut ol' with the application of little power. Attention in this connection is called to the relation of the angle iron at the, lower edge of the' bucket in respect'to the angle iron at the lower end of thecentral frame, these` angle irons forming wearing members 'and that on the bucket having a movement edgewise, nearly at right angles to the opposing surface of the other iron, so as to cntthrough the material in closing.

The interior of the-buckets is eitirely clear, no rods or other members extending across them to obstruct the space on: to be subject4 to injury or wear from contact of the material therewith when delivered into-fthe bucket. The cross shaft 27 extendsthrough the space within'the central frame, and is thus protected, and this space may be uti-` lizedv for receiving any suitable driving. mechanism, for instance, an electric motor indicated conventionally at 29. Any suitable form of differential gearing may `be combined with the axlewhen this axle` as in the present case, is a' 'live one, and-divided theme49 for purposes of turning, and this mechanism indicated conventionally at 29 may be located in the space within the frame.

l As before referred to, the plates connected with the triangular frames form a housing for the motor anddri ving gearing, and this I protects the inclosed parts from dust and weather. By tipping the vehicle, the bottom yof the supplemental frame will assume an inclined position, so ythat the lower door may Abe readily removed and access had to the interior of the frame, and the parts housed therein. The bucket frame, in its resilient vertical movement allowed by the springs, is guided by angle bars-30 secured to the side ilates and working against guide blocks 30 to the main frame.

As before stated, the main frame is composed of angle iro'n presenting a horizontal fla-nge o-r ledge at'its interior bottom edge, and vvat the curved ends of this frame draw- 'bars 31 rest on the horizontal flanges, being rame. e These draw-bars have brackets or pivoted Yat 32 to cross bars 33 on the main boxes 34V riveted to their under sides which receive bolts 35-connected with draw heads..

36, springs 37 being interposed between the boxes and collars 38 on the bolts. 'lhe drawbars are adapted to slide on the semi-circle lar ends of the main frame according as the line of draft shifts and the spring draw head provides accommodation for unevenness'inv the roadway over'which the vehicleis being drawn, it being understood that a number of these vehicles can be coupled together in a train and bevdrawn by a motor car at the fro-nt, the springdraw head being lfree to assume different angular positions '1n passing.

over uneven places. It will be understood alsoy that each vvehicle may be supplied with an independent motor and battery thereon and one or more' of these may be operatedto drive the entire train, or the vehicles may be used individually and be horse drawn .if `desired.

hicle consisting of bands 39, ,40, applied to drums l41, carried byA the wheels. These bands, a pair being used' for each wheel, are connected by pins or bolts to blocks 42 supported onthe frame and their vother ends are connected to a brake lever 43 on each' side of the -pivot 44 thereof. The brake lever, on one side, is connected with that o-n the other side by a cross bar 45. The cross bar is connected .with a rope 46 by which the brake is held olf, but when this is released, the leverl will fall and set the brake. The brakes of 'the 'several vehicles iny ,a train may be con-l nected with the one rope as in F ig. 7 so that should any vehicle become detached from the rest 'of the train, "all of the brakes throughout the seriesl of vehicles willl he set by thel'alling of ltheir brake levers. The-,rope 46 passes around a pulley 47 on'the brake le I have also provided a brake for/the ve.

reference' is made to Fig. 9, in which the mainframe is mounted upon a wheel o-r wheels indicated aty 50 at the front of the frame which frame' extends farther, forward than in the form first described, and where, as in the exam le shown, one, wheel at the front is used, t iis may answer as,the steering wheel, beingconnected with the steering post 52. A seatforthe driver is provided at 53, and the levery for dumping the buckets extends in proximity to this seat to be operl ated by the driver, who` can steer, dump, and, through a' suitable controller, he can v,control theD drive. This drive inthis form may consist of a motorconnectedwith the shaft 53 andmou'nted in the body. This shaft is connected by a chain 54'with a drive wheel 54 on the axle of the larger rear wheels. The buckets are arranged in a manner similar to those above described, and the supplemental fra-me carrying these buckets is spring mounted, and is guidedin its vertical movelnent by the angle iron bars 30, the

rear one, however, working against the rear end of the frame.

L In Fig. 10Ishow the application of my i invention to a horse drawn vehicle, a pair of small. wheelsbeing used at the front con nected with the body' by a fifth wheel, and

a draft pole being connected with the axle. In this forn the mainframe 3 is extended to.the rear and another vehicle may be atktaehed tot-his extension to be drawn along therewith. A

In another form of mylapparatus, e., like a cart', I may prefer to use .a motor in Ieach of the two wheels, a'nd as a type of l motor and transmission Whichmay be used for this purpose, I would refer to that shown, inthe patent of Church and Knudsemdated -fune 11,1907, #856,948, and'these motors can be controlled independent-ly, either being cut out or reducedin speed for turning. Se far as this part of my invention is concerned, I do notflimitjinyself to-any par-v iis ticular form of drive for the vwheels of the i cart, mentioning the Knudsen motor and transiinssion as one that might be used forthe purpose, my invention, in this respect, being broader than `the particular means used. for so lfair as I am aware, it has not been previously proposedto.provide a cart- -havng driving mechansm'tor. each wheel g eral movement and each capable of being cont-rolled independently of the other sothat no steering apparatus is necessary independent of or additional to the drive, the twofold function of propelling and. steering the vehicle according to the relative speeds of the independent drives or motors, suitable controlling devices well known in the art controlling the current to either wheel. When such a cart is used at the head of a train for steering as wellas propelling, itwill carry a battery within its triangular frame and a controller, which may be arranged on a suitable support indicated at G() in Fig. 6, .wherein also the drivers seat is shown. This controller will control thiesteering by the wheels of the front cart by reducing the speed of one in relation to the other,'or stopping or reversing one while the other 'continues to drive, and as each ot the other carts of the train may have its own motor or motors whether in the wheels or in the housing, and also its own battery, suitable controlling means will be arranged on the front cart for controlling these'moe tors for forward driving. The front cart will be coupled to the second' cart to make a composite vehicle composed of' these two carts coupledtogether. The coupling, however, will be locked against lateral swinging movement in respect to the first cart, for which purpose I provide a'pin 59 to pass down through an opening in the bar 3l, as shown in Figs. l and 6, and into an opening in the end of themain frame; This will ho d the coupling to the frame of the .first cart, thus providing, in effect, a tail bar or piece on the trent cart held centrally against latextending rearwardly and pivoted to therear 'cart at 32, because these two couplings are rigidly connected together at their meeting heads, and by this arrangement the second cart is therewith, it being understood that the coupling bar is not locked or pinned tov the front ot' the second cart, but can turn. laterally in respect thereto, while drawing it forward. Between the other carts of the train the draw-bars 231 are lockedA or similarly pinned in place at the rear of each cart to form pieces extending rearwardly, and pivotally connected with the next cart to lead the same and cause vtracking thereof with the cart next in front. As the carts are reversible end for end, openings are provided in the draw-bars and in themain frames at each end of each cart to enable either draw-bar to be pinned in place against flateral mover,...

ment, but when connected up'in a train only the rear draw-bar of each cartA 'is' pinned against lateral movement.l

,l have also provided an improved form of wheel particularly the latter performing flange 57 led by .the first cart' .in such manner as to track rigid tail adaptedfor heavy hauljirig and road building, which -will avoid breakdowns due to crystallization of the spokes and which may be repaired with ordinary facilities-and tools. The rim of the wheel is formed of stock channel iron, the spokes of vwooden beams rectangular in cross section, such as may be provided-from stock timber or scantling. The outer. ends of these fit in cast sockets riveted tothe rim and at their inner ends they fit against blocks55, one for each spoke, said blocks bearing the wheel, and being operated by the screws 57; These have nuts on one end and heads on the other by which the screws are turned for adjusting the Wedges. The wedges 56 at their inner ends bear on the hub of the wheel. The bolts pass through -a plate or formed with or fixed to' the hub, and this plate may lcarry the drum for the brake band. The bolts also pass through a face plate 58 att-he outer side of the wheel. By removing the nuts, the face plate may be removed and access had to the :wedges and spokes, and either one maybe removed and replaced, and whenthe Wheel is complete,

l on wedges .56 movable laterally-of" on the inner side ofthe wheel any spoke can be adjusted individually.

The lbolts indicated at 57 pass between the spokes and through the plates. The inner ends oi. thespokes are squared ,oii'l and the blocks 55 serve as wearing shoesl to receive l.

the pressure from4 the wedges.

While /l' have` described the buckets as I being pivotedat 'their upper ends intermediate of their length, I do inot limit myself to any particularl position for these pivots in respect to the length of the buckets, and.

indeed, thepivots may be placed at the frontiof the forward bucket rear bucket.- I

I have described and shown several speciiic forms of my invention with a view to and at the back of the indicating that the scope of my invention is not limited to any one formof apparatus, and in this connection l desire to state that divisional applications will be iiledfor the sprcihc :tor-ins and features disclosed herein, but which it is n ot possible to claim under the rules in this application.

lcverting to that part of my invention relating to the use of the carts in trains, the

train of carts can be run in either direction, it being necessary only to shift the pins which iiX the coupling bars to lthe other ends oil. said bars to secure the tracking above def'v scribed. Where a generating set is used this can be shifted from .one end of the traiinto thebther; Instead of a generating set a traction engine may be used to draw the train of carts.
